Description
Magnesium fluoride coating material is a high-performance surface coating material, which is currently the most widely used low refractive index material in the ultraviolet-near-infrared band. It is suitable for single-layer anti-reflection coatings and is also suitable for use as a low refractive index material in combination with other materials for multi-layer film filters. Magnesium fluoride coating materials have high corrosion resistance, wear resistance, and high temperature resistance, effectively resisting chemical corrosion such as acid, alkali, and salt, as well as resisting corrosion from water vapor, oxidizing gases, and high-temperature oxidation.Therefore, it is widely used in aerospace, automotive, electronics, chemical and other fields.
